HYDROCARBON-VAPOFi BURNER.

SPECIFICATION forming part of Letters Patent No. 725,796, dated April 21, 1963.

Application filed February 20, 1901. Serial No. 48,108. (No model.)

T0 aZZ whom, it may concern.-

Be it known that we, WILLIAM H. TARMON and FRANK M. THOMPSON, citizens of the United States, residing at Fort Wayne, in the county of Allen, in the State oflndiana, have invented certain new and useful Improvementsin Hydrocarbon-VaporBurners and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to improvements in hydrocarbonvapor burners, especially designed and adapted for use in sad-irons.

It is well known that in the burners now in common use in sad-irons in which hydrocarbon is employed the imperfect and irregular generation or vaporization results from the high pressure of the gas which forces the hydrocarbon forward through the burner faster than it can be perfectly vaporized and that this undue pressure is in turn produced by the overheating of the supply-pipe, which necessarily results from the common arrangement of the burner in the rear end of the iron and of the supply-pipe directly above the burner-pipe which heats the iron.

The object of our-present invention is to provide a cheap, simple, and efiicient burner which is adapted to be arranged in the forward end of the iron instead of the rear end and to be connected with the forward end of the bu rner-pipe,thereby removing the body or exposed portion of the supply-pi pe from direct contact with the flame from the burner-pipe, while at the same time a sufficient circulation of the hydrocarbon through the burner is provided for to secure a practically perfect generation under a substantially uniform degree of heat.

With this general object in view and others which will appear as the nature of the improvements is better understood the invention consists substantially in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described,

and showing the relative arrangement of the operative parts. Fig. 2 is a plan view of our improved burner. Fig. 3 is an enlarged perspective detail of our improved burner, broken away in part to show the ducts in which the fuel-gas is generated, the burnerpipe being broken away. Fig. 4 is a rear end view of the same in cross-section, showing the extension of the said passages about the burner-pipe.

All parts of our invention are ofcourse made of suitable metal.

The body 1 of the burner of proper proportions and of any desired contour is preferably as compact as possible and has its forward extremity provided with the upright screwthreaded boss 2, into which the lower end of the supply-pipe 3 is secured, the upper end thereof being surmounted by a proper oil-receptacle t of common form. The body 1 is provided upon its forward end with a longitudinal integral extension 5, having an 0blique longitudinal lug 6, in which is arranged any proper supply-valve '7, and has a pendent ing 8 in alinement with the body 1, in which is arranged a proper needle-valve 9. The said burner-body is supported in its upright position by two pendent lugs 10 and 11, the lug 10 forming a transverse foot and having a screw-threaded opening 13, in which the forward end of the burner-pipe 14 is secured. The said lug 11 also has a central circular opening adapted to snugly receive the said burner-pipe and has a sinuous fuel duct or passage 27 formed therein, passing around the said circular opening and connecting the longitudinal channel 15 of the burner leading from the supply-pipe with the parallel channel or duct 16, which leads to the said supply-valve. The burner-pipe 14 is provided upon its lower face with suitable flame-openings 17 in the usual manner, and the space 18 between the open forward end of the burner-pipe and the adjacent end of the needle-valve lug 8 forms the ignition-chamber. The bu rner-body 1 has two longitudinal openings in its rear end to admit of the boring out of the said ducts or conduits 15 and 1-6, which are closed by proper screw-plugs 19 and 20, respectively. These conduits are much smaller in cross-section than the opening in the hydrocarbon-supply pipe. The sides of the said lug 11 are preferably rectangular-,with opposite openings closed by proper screwplugs 21.

The sad-iron 22, Fig. l, in which our improved burner is mounted, may be of any proper construction having the usual thickened portion of the forward end omitted and having the forward end preferably concave, as shown, and having suitable openings therein for the protruding ends of the said supply and needle valves.

In the use of our invention in sad-irons the top plate 23 of the iron is preferably concave, as shown, with a convex integral forward portion 24, adapted to cover the said burner, leaving the body of the supply-pipe entirely upon the outside of the iron. The said sad-iron has a proper handle 28 and upper and lower ventilating lateral openings 25 and 26, respectively. Our improved burner is of course removably mounted in the iron, so that it can be lifted out upon the removal of the lid of the iron.

The operation of our improvement thus described is obvious and, briefly stated, is as follows: When the flame of the burner-pipe is ignited in the usual manner, the fuel-gas is generated from the oil which is supplied to the said passages 15 and 16 of the burnerbody 1 by the flame from the underlying forward end of the said burner-pipe. As the fuel-oil from the reservoir to reach the exit at the ignition-chamber has to pass the entire length of the said passages 15 and 16, which are directly above and within the flame, and in addition has to circulate about the burner-pipe through the said passage 27, its generation into'fuel-gas is perfectly secured, and as the burner-body in which the fuelgas is generated has much thicker walls than those of the supply-pipe in common use and is subjected to but a comparatively small portion of the flames from the burner-pipe it is evident that the generating heat in our improved burneris practically uniform, thereby securing the desired regularity in the generation of the fuel-gas. Obviously this regularity of generation in ourimproved burner is seen red by arranging the burner in the forward instead of the rear end of the sad-iron, and the generation is effected entirely within the burner itself and also by providing an extended circulation of the fuel-oil within the burner in which it is subjected to a practically uniform degree of heat.

Having thus described our invention and the manner of employing the same, what we desire to secure by Letters Patent is- 1. The combination with a sad-iron, of a burner arranged therein and comprising an elongated body provided throughout its length and at its top and bottom with longitudinal oil-ducts, a feed-pipe connected at one end of said body and extending through the sad-iron to the exterior thereof, a reservoir connected to said pipe for supplying oil to the burner, an elongated valve-casting arranged at one end of the body of the burner, and provided with a duct communicating with the lower duct of said body, a supplyvalve arranged at the juncture of said ducts, a needle-valve also carried by said casting for controlling the vapor discharged therefrom, perforated lugs carried by the burnerbody and depending therefrom, one of said lugs being provided with a sinuous duct extending around the perforation of said lug and connecting the upper and lower longitudinal ducts of the burner-body to provide a circuitous passage for the oil in its flow between said ducts, and a burner-tube arranged in the perforations of said lugs, and extending longitudinally of the burner-body, said burner-tube being in alinement with the valve-casting of the burner-bod y and receiving the vapor discharged therefrom.

2. The combination with a sad-iron, of a burner arranged therein and comprising an elongated body provided throughout its length and at its top and bottom with longitudinal oil-ducts, a feed-pipe connected at one end of said body and extending through the sad-iron to the exterior thereof, a reservoir connected to said pipe for supplying oil to the burner, an elongated valve-castingarranged at one end of the body of the burner and at a point beneath the bottom thereof, said casting being provided with a duct communicating with the lower duct of said body, a supply-valve arranged at the juncture of said (i ucts, a needle-valve also carried by said casting for controlling the vapor discharged therefrom, said supply and needle valves projecting through the sad-iron to the exterior thereof, perforated lugs carried by the burner body and depending therefrom, one of said lugs being provided with a sinuous duct extending around the perforation of said lug and connecting the upper and lower longitudinal ducts of the burner-body to provide a circuitous passage for the oil inits flow between said ducts, and a burner-tube arranged in the perforations of said lugs and extending longitudinally of the burner-body, said bu rner-tube being in alinement with the valve-casting of the burner-body and receiving the vapor discharged therefrom.
